Ivan Andika updated HDDS-9322:
------------------------------
Target Version/s: 2.0.0, 1.4.2
> Remove duplicate containers when loading volumes on a datanode
> --------------------------------------------------------------
>
> Key: HDDS-9322
> URL: https://issues.apache.org/jira/browse/HDDS-9322
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.0.0
>
>
> Prior to HDDS-5032, if the same container is found on multiple volumes, then
> the second volume to load it fails the entire volume.
> After HDDS-5032, the exception is caught so the volume doesn't fail, but
> depending on which container is loaded faster, either one of the replicas
> could win. Over several restarts, the container on either volume could be the
> one loaded, potentially resulting in inconsistencies.
> This change catches the error, and then removes one of the duplicates based
> on the BCSID. The container with the largest BCSID is the one kept, while the
> other is removed.
> This will free the disk space taken by the duplicate container, and also
> avoid the chance of a different copy being loaded on each restart.
